Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel installation, specifically an adjustable photovoltaic panel installation frame. Background Technology

[0002] Photovoltaic power generation is one of the clean power generation methods of the future, and it is of great significance for improving the environment, promoting energy upgrading and technological progress, and advancing the healthy development of the photovoltaic industry. Photovoltaic modules generate electricity by relying on sunlight, and the scale of power generation is positively correlated with the area of ​​the photovoltaic modules. Large-scale application of photovoltaic power generation depends on the large-area installation of photovoltaic modules. Based on international experience, integrating photovoltaic power generation with buildings can solve the problem of installation area. This solution has also been applied to some extent in my country. Specifically, it generally involves installing photovoltaic modules on the rooftops of existing buildings. This installation method solves the space problem for photovoltaic power generation to a certain extent.

[0003] When photovoltaic (PV) panels are installed on building roofs, their surfaces accumulate dust due to years of exposure, blocking some light from reaching the solar cells and reducing the panel's light transmittance. Current technology does not readily utilize rainwater for cleaning, resulting in a waste of natural resources. This forces the use of tap water for cleaning. However, existing cleaning methods lack the ability to adjust the water flow's impact force. When water is applied close to the PV panel, excessive force can cause friction and scratches when it hits dust. Furthermore, inadequate surface treatment after cleaning leaves water stains, creating uneven coverage and hindering solar energy absorption.

[0004] Therefore, the present invention provides an adjustable photovoltaic panel mounting frame. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problem that when photovoltaic (PV) panels are installed on building roofs, their surfaces accumulate dust due to prolonged exposure, blocking some light from reaching the solar cells and reducing the panel's light transmittance. Current technologies do not readily utilize rainwater for cleaning, resulting in a waste of natural resources. This forces the use of tap water for cleaning, but existing methods lack adjustable water flow force. Excessive water flow near the PV panel can cause friction and scratches when it hits dust, and poor surface treatment after cleaning leaves water stains that unevenly cover the panel, hindering solar energy absorption.

[0011] Preferably, two hot air blowers are symmetrically fixedly connected to the side of the first extrusion plate away from the slide plate, and both hot air blowers are installed at an angle.

Two extension plates are symmetrically fixedly connected to the top of the filter plate and above the water inlet.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The adjustable photovoltaic panel mounting frame of the present invention, through the cooperation of the inclined mounting plate and the annular side plate, can collect rainwater and filter the rainwater through the set water circulation component to prevent the rainwater from being mixed with dust and other impurities. The set guide plate guides the rainwater falling from the first and second water outlets so that the rainwater can fall on the highest point of the filter plate, thereby prolonging the residence time of the rainwater on the filter plate and preventing the rainwater from sliding directly off the inclined surface of the filter plate. The collected rainwater sprayed by the nozzle can wash the dust on the photovoltaic panel, thus effectively utilizing the rainwater in nature and making it more energy-saving and environmentally friendly.

[0018] 2. The adjustable photovoltaic panel mounting frame of the present invention, through the setting of the adjustment component, reduces the water pressure of the nozzle when rinsing the area near the photovoltaic panel to avoid the water flow from strongly impacting dust and causing scratches on the photovoltaic panel. When rinsing the area far from the photovoltaic panel, the setting of the adjustment component increases the water pressure of the nozzle to avoid insufficient water pressure to rinse the dust in the area far from the photovoltaic panel.

[0019] 3. The adjustable photovoltaic panel mounting frame of the present invention can wipe away water on the photovoltaic panel by controlling the reciprocating lateral movement of the sponge pad, preventing excessive water accumulation on the photovoltaic panel. Moreover, after each unidirectional movement, the sponge pad can process the rainwater it absorbs, maintaining the water absorption effect of the sponge pad on the photovoltaic panel.

[0020] 4. The adjustable photovoltaic panel mounting frame of the present invention uses a hot air blower to dry the photovoltaic panel, avoiding the formation of water stains on the photovoltaic panel. When fallen leaves accumulate on the photovoltaic panel, the hot air blown by the hot air blower can blow the fallen leaves and other debris away from the photovoltaic panel. The arc-shaped guide plate wraps the hot air blown by the hot air blower, preventing the hot air from hitting the photovoltaic panel and quickly dissipating upwards, thus improving the drying effect of the hot air on the photovoltaic panel. Furthermore, under the guiding effect of the concave surface of the guide plate, the overflowing hot air can flow along the surface of the photovoltaic panel, making the drying effect of the hot air even better.

[0021] 5. The adjustable photovoltaic panel mounting frame of the present invention uses a hydraulic cylinder to control the slider to move up and down to adjust the angle of the photovoltaic panel. When the photovoltaic panel is rotated downward, several protrusions cooperate with the slots of the filter plate to make the filter plate vibrate continuously, which facilitates the shaking off of dust and other particles filtered on the filter plate and prevents dust and other particles from adhering to the filter plate and affecting the filtration effect of rainwater.

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0038] like Figures 1 to 13As shown, the present invention provides a technical solution: an adjustable photovoltaic panel mounting frame, including a water tank 1, a support frame 2 fixedly connected to the top of the water tank 1, a mounting plate 3 rotatably connected to one end of the support frame 2, a hydraulic cylinder 4 fixedly mounted on the top of the water tank 1, a slider rotatably connected to the output end of the hydraulic cylinder 4, the slider being slidably connected to the mounting plate 3, two photovoltaic panels 5 symmetrically arranged on the top of the mounting plate 3, an annular side plate 6 fixedly connected to the top of the mounting plate 3, a horizontal plate 7 fixedly connected to one side of the annular side plate 6, a support plate 8 fixedly connected to the top of the horizontal plate 7, and the outer wall of the support plate 8... Two brackets 9 are symmetrically fixedly connected, and a rotating shaft 10 is rotatably connected between the two brackets 9. Several nozzles 11 are fixedly connected at equal intervals on the outer wall of the rotating shaft 10. An adjustment component is provided on the top of the horizontal plate 7. A water pump 12 is fixedly installed on one side of the water tank 1. A water inlet pipe 13 is fixedly connected to the input end of the water pump 12. One end of the water inlet pipe 13 extends into the interior of the water tank 1. Several water outlet pipes 14 are fixedly connected to the output end of the water pump 12. The water outlet pipes 14 are connected to the nozzles 11. A first water outlet 37 is opened inside the mounting plate 3. A water circulation component is provided on the top of the water tank 1.

[0039] Through the above technical solution, the hydraulic cylinder 4 is activated, and the output end of the hydraulic cylinder 4 drives the slider to move upward, causing the mounting plate 3 to rotate along the support frame 2. This adjusts the tilt angle of the mounting plate 3, allowing the photovoltaic panel 5 to face the sunlight and improve the absorption effect of solar energy. When it rains, the tilted mounting plate 3 cooperates with the annular side plate 6 to collect rainwater. The rainwater slides down the inclined surface of the mounting plate 3 and is discharged from the mounting plate 3 through the first water outlet 37. The rainwater is filtered by the water circulation component to prevent dust and other impurities from being mixed in with the rainwater. The filtered rainwater enters the water tank 1 for collection. When the photovoltaic panel 5 is exposed for a long time, dust accumulates. Then, the water pump 12 is started to draw the rainwater collected in the water tank 1 out along the inlet pipe 13. The drawn rainwater enters the nozzle 11 through the outlet pipe 14 and is sprayed out through the nozzle 11 to clean the photovoltaic panel 5. This effectively utilizes the rainwater in nature, making it more energy-efficient and environmentally friendly. When rinsing the area near the photovoltaic panel 5, the water pressure of the nozzle 11 is reduced by the set adjustment component to avoid the water flow hitting the dust and other objects with strong impact, which could cause the dust to scratch the photovoltaic panel 5. When rinsing the area far from the photovoltaic panel 5, the water pressure of the nozzle 11 is increased by the set adjustment component to avoid insufficient water pressure to rinse the dust far from the photovoltaic panel 5.

[0040] Specifically, the adjustment assembly includes an electric telescopic rod 16, which is located on the top of the horizontal plate 7 and rotatably connected to it. A positioning rod 15 is fixedly connected to the outer wall of the rotating shaft 10. The output end of the electric telescopic rod 16 is rotatably connected to the positioning rod 15. Fixing plates 17 are fixedly connected to both sides of the nozzle 11. First sliding shafts 18 are slidably connected to the inner walls of the two fixing plates 17. Top plates 21 are fixedly connected to the tops of the two first sliding shafts 18. A baffle 22 is fixedly connected between the two top plates 21. A slot 23 is opened on the top of the nozzle 11. The baffle 22 fits against the inner wall of the slot 23. First limiting blocks 20 are fixedly connected to the bottoms of the two first sliding shafts 18. A first spring 19 is sleeved on the outer wall of the first sliding shaft 18. The top of the first spring 19 is fixedly connected to the top plate 21, and the bottom of the first spring 19 is fixedly connected to the fixing plate 17. A limiting plate 50 is fixedly connected to the outer wall of the support plate 8 and above the baffle 22.

[0041] With the above technical solution, when rinsing the distant part of the photovoltaic panel 5, the positioning rod 15 is rotated upward by the electric telescopic rod 16, which drives the nozzle 11 to rotate upward. The top of the baffle 22 presses against the limiting plate 50. Under the push of the limiting plate 50, the baffle 22 slides inside the nozzle 11. At this time, the diameter of the nozzle 11 gradually decreases, which increases the water pressure of the nozzle 11, allowing the water to spray further and increasing the impact force of the water flow. While the baffle 22 slides inside the nozzle 11, it presses the first spring 19. When rinsing the near part of the photovoltaic panel 5, the positioning rod 15 is rotated downward by the electric telescopic rod 16, which drives the nozzle 11 to rotate downward. Under the action of the first spring 19, the baffle 22 moves back, which gradually increases the diameter of the nozzle 11, reduces the water pressure inside the nozzle 11, and thus reduces the impact force of the water flow, reducing the impact force of the nozzle 11 on the near part of the photovoltaic panel 5.

[0042] Specifically, a motor 24 is fixedly installed on one side of the annular side plate 6. The output end of the motor 24 passes through the annular side plate 6 and is fixedly connected to a lead screw 25. The outer wall of the lead screw 25 is connected to a slide plate 26 through a lead screw nut pair. The slide plate 26 is slidably connected to the annular side plate 6. Two second sliding shafts 27 are symmetrically slidably connected to the inner wall of the slide plate 26. A first extrusion plate 30 is fixedly connected to one end of the two second sliding shafts 27. Two sponge pads 31 are symmetrically fixedly connected to the side of the first extrusion plate 30 near the slide plate 26. A second limiting block 28 is fixedly connected to the other end of each of the two second sliding shafts 27. A second spring 29 is sleeved on the outer wall of the second sliding shaft 27. One end of the second spring 29 is fixedly connected to the slide plate 26, and the other end of the second spring 29 is fixedly connected to the first extrusion plate 30. A through groove for use with the lead screw 25 is opened inside the first extrusion plate 3. A second water outlet 38 is opened on the top of the mounting plate 3 and on the side away from the first water outlet 37.

[0043] With the above technical solution, after rinsing the photovoltaic panel 5, the motor 24 is started, which drives the lead screw 25 to rotate, causing the slide plate 26 to move towards the side closer to the first water outlet 37. As the slide plate 26 moves, it also drives the first squeezing plate 30 and the sponge pad 31 to move. The moving sponge pad 31 wipes away the water accumulated on the photovoltaic panel 5, preventing excessive water accumulation. When the first squeezing plate 30 moves to a position close to the annular side plate 6, it is prevented from moving further due to the limitation of the annular side plate 6. As the slide plate 26 continues to move, the sponge pad 31 between the slide plate 26 and the first squeezing plate 30 is squeezed, expelling the rainwater absorbed by the sponge pad 31. The rainwater squeezed out of the sponge pad 31 flows out along the first water outlet 37 and re-enters the water tank 1, thus recycling the water and saving water resources.

[0044] Specifically, the inner wall of the skateboard 26 is symmetrically connected to two push rods 33, and one end of each push rod 33 is fixedly connected to a second extrusion plate 32, which is in contact with the outer wall of the sponge pad 31.

[0045] Through the above technical solution, after the rainwater is squeezed out of the sponge pad 31, the motor 24 controls the slide plate 26 to move back. At this time, the sponge pad 31 can wipe the photovoltaic panel 5 again and further absorb the rainwater on the photovoltaic panel 5. When the slide plate 26 moves to the other side of the annular side plate 6, under the pressure of the annular side plate 6, the top rod 33 slides in the slide plate 26, pushing the second extrusion plate 32 to move towards the first extrusion plate 30, squeezing out the rainwater absorbed by the sponge pad 31 again. At this time, the rainwater squeezed out from the sponge pad 31 falls from the second outlet 38 and enters the water tank 1 for recycling.

[0046] Specifically, a barrier plate 36 is fixedly connected to the top of the first extrusion plate 30, and the barrier plate 36 is set in an arc shape.

[0047] With the above technical solution, when the spray nozzle 11 is used to rinse the photovoltaic panel 5, the first squeezing plate 30 is controlled to move to the second water outlet 38. The set baffle plate 36 can block the rainwater sprayed by the spray nozzle 11, preventing the rainwater from splashing to one side. Under the wrapping of the baffle plate 36 and the annular side plate 6, the sprayed rainwater can flow back down along the slope of the mounting plate 3 to perform secondary cleaning of the photovoltaic panel 5, and the effect on dust is better.

[0048] Specifically, two hot air blowers 34 are symmetrically fixedly connected to the side of the first extrusion plate 30 away from the slide plate 26, and both hot air blowers 34 are installed at an angle.

[0049] Through the above technical solution, after the sponge pad 31 absorbs the rainwater remaining on the photovoltaic panel 5, the hot air blower 34 is started to blow hot air onto the surface of the photovoltaic panel 5, thereby drying the photovoltaic panel 5, avoiding the formation of water stains on the photovoltaic panel 5, and when fallen leaves accumulate on the photovoltaic panel 5, the hot air blown by the hot air blower 34 can blow the fallen leaves and other objects away from the photovoltaic panel 5.

[0050] Specifically, a guide plate 35 is fixedly connected to the top of the hot air blower 34, and the guide plate 35 is set in an arc shape.

[0051] Through the above technical solution, the hot air blown out by the hot air blower 34 is wrapped by the arc-shaped guide plate 35, which prevents the hot air from hitting the photovoltaic panel 5 and then quickly drifting upwards, thus improving the drying effect of the hot air on the photovoltaic panel 5. Furthermore, under the guiding effect of the concave surface of the guide plate 35, the overflowing hot air can flow along the surface of the photovoltaic panel 5, making the drying effect of the hot air even better.

[0052] Specifically, the water circulation assembly includes two inlets 44, both of which are located on the top of the water tank 1 and below the first outlet 37 and the second outlet 38, respectively. Four third sliding shafts 40 are symmetrically slidably connected to the top of the water tank 1. Filter plates 43 are fixedly connected to the top of the four third sliding shafts 40. The top of the filter plates 43 is set as a symmetrical inclined surface, and a slot is opened on the top of the filter plates 43. Third limiting blocks 42 are fixedly connected to the bottom of each of the four third sliding shafts 40. Third springs 41 are sleeved on the outer wall of the third sliding shafts 40. The top of the third springs 41 is fixedly connected to the filter plates 43, and the bottom of the third springs 41 is fixedly connected to the water tank 1.

[0053] With the above technical solution, rainwater falling from the first outlet 37 and the second outlet 38 lands on the inclined surface of the filter plate 43. The rainwater is filtered by the filter plate 43, so that dust and other impurities remain on the filter plate 43 and slide down along the inclined surface of the filter plate 43. The filtered rainwater falls through the filter plate 43 and enters the water tank 1 for storage through the inlet 44.

[0054] Specifically, a connecting shaft 46 is fixedly connected to the outer wall of the output end of the hydraulic cylinder 4. Two fixed shafts 47 are symmetrically fixedly connected to the bottom of the connecting shaft 46. Several protrusions 49 are equidistantly slidably connected to the inner wall of the fixed shaft 47. The top and bottom of the protrusions 49 are both set as inclined surfaces. A fourth spring 48 is fixedly connected to one end of the protrusion 49. The fourth spring 48 is fixedly connected to the fixed shaft 47. The elastic force of the fourth spring 48 is greater than that of the third spring 41.

[0055] Through the above technical solution, the hydraulic cylinder 4 controls the slider to move up and down, adjusting the angle of the photovoltaic panel 5. When the hydraulic cylinder 4 controls the photovoltaic panel 5 to rotate downward, it drives the fixed shaft 47 to move downward, causing the protrusion 49 to move downward. When the inclined surface of the protrusion 49 presses against the slot of the filter plate 43, it is stuck. As the fixed shaft 47 moves downward, it pushes the filter plate 43 downward, pressing the third spring 41. When the third spring 41 is pressed to its limit, under the pressure of the filter plate 43, the protrusion 49 moves into the interior of the fixed shaft 47, pressing the fourth spring 48. When the protrusion 49 disengages from the filter plate 43, under the action of the third spring 41, it drives the filter plate 43 to vibrate upward. This process is repeated. Through the several protrusions 49, when the photovoltaic panel 5 is controlled to rotate downward, the filter plate 43 vibrates continuously, which facilitates the shaking off of dust and other particles filtered on the filter plate 43, preventing dust and other particles from adhering to the filter plate 43 and affecting the filtration effect of rainwater.

[0056] Specifically, a flow guiding component is provided at the bottom of the mounting plate 3, below the first outlet 37 and the second outlet 38. The flow guiding component includes two flow guiding plates 39, which are symmetrically fixedly connected to the bottom of the mounting plate 3. Both flow guiding plates 39 are installed at an angle, and a sliding groove is opened on the top of both flow guiding plates 39. Two extension plates 45 are symmetrically fixedly connected to the top of the filter plate 43, above the inlet 44.

[0057] Through the above technical solution, the rainwater falling from the first outlet 37 and the second outlet 38 is guided by the deflector plate 39, so that the rainwater can fall on the highest point of the filter plate 43, thereby extending the residence time of the rainwater on the filter plate 43 and preventing the rainwater from sliding directly from the slope of the filter plate 43. The two extension plates 45 are provided to wrap the rainwater falling on the filter plate 43 and prevent the rainwater from splashing everywhere.

[0058] In use, the hydraulic cylinder 4 is activated, and its output end drives the slider upward, causing the mounting plate 3 to rotate along the support frame 2. This adjusts the tilt angle of the mounting plate 3, allowing the photovoltaic panel 5 to face the sunlight and improve its solar energy absorption. During rain, the tilted mounting plate 3, in conjunction with the annular side plate 6, collects rainwater. The rainwater slides down the slope of the mounting plate 3 and exits through the first outlet 37 and the second outlet 38. The rainwater falling from the first outlet 37 and the second outlet 38 lands on the slope of the filter plate 43, where it is filtered. Dust and other impurities remain on the filter plate 43 and slide down its slope. The filtered rainwater then passes through the filter plate 43 and through the inlet 4. 4. Rainwater enters the water tank 1 for storage. The guide plate 39 directs the rainwater falling from the first outlet 37 and the second outlet 38, allowing it to fall onto the highest point of the filter plate 43. This prolongs the residence time of the rainwater on the filter plate 43, preventing it from sliding directly off the slope of the filter plate 43. Two extension plates 45 help to contain the rainwater falling on the filter plate 43, preventing splashing. When the hydraulic cylinder 4 controls the photovoltaic panel 5 to rotate downwards, it drives the fixed shaft 47 to move downwards, causing the protrusion 49 to move downwards. When the slope of the protrusion 49 presses against the slot of the filter plate 43, it is locked. As the fixed shaft 47 moves downwards, it pushes the filter plate 43 downwards, compressing the third spring 41. When the third spring 41 is compressed to its limit, the filter plate... Under the pressure of 43, the protrusion 49 moves inward toward the fixed shaft 47, pressing the fourth spring 48. When the protrusion 49 disengages from the filter plate 43, the filter plate 43 vibrates upward under the action of the third spring 41. This process repeats, and through the several protrusions 49, the filter plate 43 vibrates continuously while the photovoltaic panel 5 rotates downward, making it easier to shake off the dust and other particles filtered on the filter plate 43, preventing dust and other particles from adhering to the filter plate 43 and affecting the filtration effect on rainwater. When the photovoltaic panel 5 is exposed for a long time and accumulates dust, the water pump 12 is started to draw the rainwater collected in the water tank 1 out along the inlet pipe 13. The drawn rainwater enters the nozzle 11 along the outlet pipe 14 and is sprayed out through the nozzle 11 to clean the photovoltaic panel 5, thereby effectively utilizing the rainwater from nature. This method is more energy-efficient and environmentally friendly. When rinsing areas far from the photovoltaic panel 5, the electric telescopic rod 16 controls the positioning rod 15 to rotate upwards, causing the nozzle 11 to rotate upwards. The top of the baffle 22 presses against the limiting plate 50. Under the counter-push of the limiting plate 50, the baffle 22 slides inside the nozzle 11. At this time, the diameter of the nozzle 11 gradually decreases, increasing the water pressure and allowing the water flow to spray further, thus increasing the impact force of the water flow and preventing insufficient water pressure from failing to rinse dust far from the photovoltaic panel 5. While the baffle 22 slides inside the nozzle 11, it presses the first spring 19. When rinsing areas near the photovoltaic panel 5, the electric telescopic rod 16 controls the positioning rod 15 to rotate downwards, causing the nozzle 11 to rotate downwards. Under the action of the first spring 19...The baffle 22 is moved back, gradually increasing the diameter of the nozzle 11, reducing the water pressure inside the nozzle 11, and thus reducing the impact force of the water flow. This reduces the impact force of the nozzle 11 on the photovoltaic panel 5, preventing the water flow from strongly impacting dust and other particles, which could cause scratches on the photovoltaic panel 5. After rinsing the photovoltaic panel 5, the motor 24 is started, driving the lead screw 25 to rotate, causing the slide plate 26 to move towards the side closer to the first water outlet 37. As the slide plate 26 moves, it also moves the first squeezing plate 30 and the sponge pad 31. The moving sponge pad 31 wipes away the water accumulated on the photovoltaic panel 5, preventing excessive water accumulation. When the first squeezing plate... When the pressure plate 30 moves to a position close to the annular side plate 6, the first pressing plate 30 cannot move due to the limitation of the annular side plate 6. As the sliding plate 26 continues to move, the sponge pad 31 between the sliding plate 26 and the first pressing plate 30 is squeezed, expelling the rainwater absorbed by the sponge pad 31. The rainwater squeezed out of the sponge pad 31 flows out along the first outlet 37 and re-enters the water tank 1, thus recycling and saving water resources. After squeezing out the rainwater from the sponge pad 31, the sliding plate 26 is moved back by the motor 24. At this time, the sponge pad 31 can wipe the photovoltaic panel 5 again, further absorbing the rainwater on the photovoltaic panel 5. When the sliding plate 26 moves to When the annular side plate 6 is pressed on the other side, the top rod 33 slides inside the slide plate 26, pushing the second pressing plate 32 towards the first pressing plate 30, squeezing out the rainwater absorbed by the sponge pad 31 again. At this time, the rainwater squeezed out from the sponge pad 31 falls from the second outlet 38 and enters the water tank 1 for recycling. When the nozzle 11 is used to wash the photovoltaic panel 5, the first pressing plate 30 is controlled to move to the second outlet 38. The barrier plate 36 can block the rainwater sprayed from the nozzle 11, preventing the rainwater from splashing to one side. Under the wrapping of the barrier plate 36 and the annular side plate 6, the sprayed rainwater is contained. Water can flow downwards along the slope of the mounting plate 3, performing a secondary cleaning of the photovoltaic panel 5 and achieving better dust removal. After the sponge pad 31 absorbs the residual rainwater on the photovoltaic panel 5, the hot air blower 34 is activated to blow hot air onto the surface of the photovoltaic panel 5, thereby drying the photovoltaic panel 5 and preventing water stains from forming on it. The curved guide plate 35 envelops the hot air blown by the hot air blower 34, preventing the hot air from hitting the photovoltaic panel 5 and quickly dissipating upwards, thus improving the drying effect of the hot air on the photovoltaic panel 5. Furthermore, the concave surface of the guide plate 35 guides the overflowing hot air to circulate along the surface of the photovoltaic panel 5, further enhancing the drying effect.
